I have a Zalman 750-Watt PSU right now, and it is well constructed and has never given me any problems. However, it seems this PSU is fast approaching its age in terms of the new hardware requiring more and more wattage. Although I do not plan on building another system for about 3 years, what are some of the absolute best PSU's on the market right now? I have had my eye on the Corsair 1000 Watt one. Low price and all reviews have said its an absolute killer. Now, if they'd make a 1200 Watt... Anyone have others to add?
